Minilaparoscopic sentinel lymph node biopsy is a feasible technique for early-stage endometrial cancer (EC) staging. This 3-mm approach showed comparable results to standard 5-mm laparoscopy, with no significant differences in detection rates or complications.

Area of Science:

  • Gynecologic Oncology
  • Minimally Invasive Surgery
  • Surgical Pathology

Background:

  • Sentinel lymph node (SLN) detection is crucial for staging early-stage endometrial cancer (EC).
  • Minimally invasive surgical techniques aim to reduce patient morbidity while maintaining oncologic efficacy.
  • Comparing different laparoscopic instrument sizes for SLN detection in EC is important for optimizing surgical outcomes.

Purpose of the Study:

  • To compare the efficacy and safety of 3-mm minilaparoscopy versus standard 5-mm laparoscopy for SLN detection in apparent early-stage EC.
  • To evaluate operative parameters, SLN detection rates, and complication incidence between the two techniques.

Main Methods:

  • A retrospective study was conducted at two academic centers, comparing 3-mm minilaparoscopy (n=15) with standard 5-mm laparoscopy (n=23) for EC staging.

  • All patients underwent hysterectomy with bilateral salpingo-oophorectomy and SLN detection using indocyanine green fluorescence imaging.
  • Data on demographics, tumor characteristics, operative time, blood loss, hospital stay, and complications were collected and analyzed.

    • Main Results:

    • No significant differences were observed in demographic or tumor characteristics between the 3-mm and 5-mm groups.
    • Bilateral SLN detection rates were similar: 73.3% in the 3-mm group and 73.9% in the 5-mm group.
    • Operative time, blood loss, hemoglobin drop, hospital stay, and complication rates were comparable. One patient in the 5-mm group had a positive SLN (micrometastasis).

    Conclusions:

    • 3-mm minilaparoscopic SLN biopsy is a promising and feasible technique for staging early-stage EC.
    • The minilaparoscopic approach demonstrated comparable efficacy to standard laparoscopy for SLN detection.
    • Further research is warranted to explore the potential benefits of 3-mm instruments in EC staging.
